Subject[PATCH v2 10/10] arm64: allwinner: a64: add dma controller references to spi nodes
Date
The spi controller nodes omit the dma controller/channel references, add
it.

This does not yet enable DMA for SPI transfers, as the spi-sun6i driver
lacks support for DMA, but always uses PIO to the FIFO.
